GOSHEN Â? Fred Mott received the maximum sentence of 60 years in prison Thursday for the murder of a Wakarusa teenager.

Earlier this month, a jury in Goshen found Mott guilty of killing 16-year-old Kari Nunemaker in 1991.

Mott says he is innocent. He's already serving several life sentences in California for rape, so he says he has no reason to lie.

But Kari's family is not convinced. They say this case is done.

After the guilty verdict came down earlier this month, Mott spoke out to WSBT cameras.

"If I had lawyers, I'd had a better verdict. They didn't tell the story. You don't know what happened," exclaimed Mott. "You don't know what happened. I was supposed to tell you what happened, wasn't I?"

But on the day of his sentencing, Mott saved his words for the courtroom.

He told the judge he is a rapist but not a murderer. He also called the testimony during his trial all lies.

"We're not dealing with a person who thinks rationally like we do," said Elkhart County Prosecutor Curtis Hill.

Perhaps the biggest blow in Mott's speech was the sympathy he expressed to Kari's family.

"I do not accept it because we know what he did and that makes him even more of a coward," said Shirley Nunemaker, Kari's mom.

Kari was raped, choked to death and left in a park.

Mott was a suspect from the beginning, but it was DNA testing in 2005 that finally prompted prosecutors to charge him.

"That was the nail in the coffin, so to speak," said Doug Snow of the DNA evidence. Snow served as an alternate on the jury.

In the end, it gave Kari's family what they had hoped for.

"It's not perfect justice Â? there's no such thing as perfect justice when you lose a loved one," said Hill. "But in terms of learning what occurred, they now have the answers that were elusive for so many years."

"We're glad it's done," Shirley Nunemaker said. "We know what happened and we know Kari's happy and we're going to see her someday. That's the only hope we have."
